Plastic bellows production line is a special plastic pipe production line equipment for producing plastic bellows (including single-wall bellows and double-wall bellows). The plastic bellows produced by it must meet the following technical indicators:
1. Raw material requirements
HDPE (high density polyethylene), PP (polypropylene), and PVC (polyvinyl chloride) particles can be used for the plastic bellows. The requirements must be the original granular raw materials. It is strictly prohibited to use powdered and re-granulated granular raw materials. HDPE must meet GB / T11116 standard requirements, and PP must meet GB / T18742.1 standard.
2. Color appearance requirements
The appearance of the plastic bellows should be smooth, with small roundness, uniform color, and no cracks, bubbles, cracks, lumps, or scratches affecting the use of separators are allowed on the inner and outer walls.
3.Ring steel requirements
The stiffness of the double-walled plastic bellows ring should not be less than 6 kN / m2. The ring stiffness of the prestressed plastic bellows is not less than 4 kN / m2.
4, flexibility requirements
After the plastic corrugated pipe is repeatedly bent five times according to the prescribed bending method, the change in cross-sectional diameter should not be greater than 10% of the original diameter.
5. Impact resistance requirements
The maximum allowable TIR value of the true impact rate of the plastic bellows drop weight impact test is 1/10.
6.Local lateral load
Plastic corrugated pipe When the corrugated pipe is subjected to a lateral load of 500N, the surface of the pipe will not crack, and the remaining deformation of the pipe 5 minutes after unloading shall not exceed 10% of the nominal inner diameter of the pipe.
7.Sealing requirements for bellows connection
There is no water leakage inside the corrugated pipe connection, and the bonding between the pipes should be tight, no cracks, no loosening
